Darren,
Yes, I'm seeing this too since moving to VFP8. We're using VFE7.5b framework and it seems to happen mostly in cfield:value_assign on the REPLACE command. It makes no sense at all why this would be happening. Unlike you, our's is using remote views against SQL. We are also using localized "views only" dbc's so the DBC's themselves are not being shared by users on the network. I think we have buffermode = 3 on a lot of these views. I'd sure like to know what causes this and how to fix it. It's showing up more frequently in the errorlog, but I cannot successfully reproduce it in the test or developement environments.
